CDC73

L000002792, YLR418C
Component of the Paf1p complex; binds to and modulates the activity of RNA polymerases I and II; required for expression of certain genes, modification of some histones, and telomere maintenance; involved in transcription elongation as demonstrated by the G-less-based run-on (GLRO) assay; protein abundance increases in response to DNA replication stress; human homologue, parafibromin, is a tumour suppressor linked to breast, renal and gastric cancers

Co-purification

An interaction is inferred from the identification of two or more protein subunits in a purified protein complex, as obtained by classical biochemical fractionation or affinity purification and one or more additional fractionation steps.

Publication

Ctr9, Rtf1, and Leo1 are components of the Paf1/RNA polymerase II complex.

Mueller CL, Jaehning JA

The Saccharomyces cerevisiae Paf1-RNA polymerase II (Pol II) complex is biochemically and functionally distinct from the Srb-mediator form of Pol II holoenzyme and is required for full expression of a subset of genes. In this work we have used tandem affinity purification tags to isolate the Paf1 complex and mass spectrometry to identify additional components. We have established that Ctr9, ... [more]

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
